On Thursday, a town hall meeting hosted by Al Sharpton and the National Action Network to address gun violence exploded into a revolt against “Chicago Machine” politics, Mayor Rahm Emanuel, and the aldermen in City Hall, with panel and audience members calling to vote out their elected officials.

One 82-year-old preacher even called for “Tea Party” style meetings in some of Chicago’s south side communities such as Altgeld Gardens and Trumbull Park.
